THe thing about scolding them, telling them No, i've heard.. they might get it confused with pooping.
so they might think you are scolding them for pooping. which i don't want to do because he just started pooping onthe pads again 100% lol..
i posted this on another site, and they told me this..

often it's just something puppies do and they get over it. you can try feeding him some pineapple, which is supposed to make the poop taste less appealing (but doesn't poop already taste bad?

). it might not work, but it's harmless at the very least.
